The rate that stall rate and production line heat scatter and disappear naturally is unequal, and product pretreatment fluid necessarily requires a stable temperature
Degree, this just proposes different recovery ratio requirements in Various Seasonal to Waste Heat Recovery, and summer requires the rate of recovery low, and winter requires
The rate of recovery is high, and system must have intelligent regulatory function to the rate of recovery.And traditional recuperation of heat mode does not have intelligence and adjusts function
The inadaptability in season can be brought, the heat recovery efficiency for especially still maintaining intrinsic when environment temperature is high will allow circulation
Fluid temperature into exchanger persistently increases the degree even to gasification, the gas inside heat exchanger when the situation that gasifies is more serious
It presses through high and is counteracted that the intake pressure of circulating pump can directly result in system and stop transport completely, gas not resulting in system and stopping completely
Erosion will lead to fast erosion inside pipeline and heat exchanger and cause to leak, once leakage, liquid can flow backward into general in oven
Cause great work safety accident and serious damage finished product quality.
